Families with children are a vulnerable group that is disproportionately affected by evictions. One of the main reasons for these evictions is the housing shortage in the society that causes families with children ending up homeless. In such cases, the children who are evicted often live with relatives or are placed in accommodation arranged by the social services. The new circumstances lead to the children losing their social contacts and experiencing psychological stress that caused the social services to carry out eviction prevention work to reduce the evictions that occur in society. Therefore, this essay aims to explore the challenges and obstacles experienced by professionals in social services when they work against evictions of children and families with children. This study is a qualitative study and seven professionals in social services have been interviewed for this study. The interview material has been analyzed using a thematic analysis and two different theories. These theories are theory of street-level bureaucracy, social psychological theory of justice. By analyzing the interview material, we have come up with four themes: living conditions of families with children, expertness and professionalism, eviction prevention efforts and organizational conditions at work. These themes explore the living conditions and housing situation of families with children and how professionals in social services work with evictions of children and families with children. Furthermore, the themes also shed light on how organizational conditions affect the scope and professionalism of social workers and what challenges they experience. Thus, the study concludes that social services need rapid and long-term efforts to be able to carry out successful eviction prevention work. In addition, social services need to apply a strong child-centred perspective and more effective efforts that focus on client-oriented contact depending on each family’s unique situation.
